Spectral and antimicrobial studies on novel ligand and its co-ordination polymers

A novel ligand 2,5-bis(4-methoxyphenylcarbamoyl)terephthalicacid (BMPCT) was prepared from 1,2,4,5-benzenetetracarboxylicdianhydride (pyromellitic dianhydride - PMDA) and 4-methoxyaniline (p-anisidine). Various coordination polymers of BMPCT were also prepared using Mn(II), Fe(II), Co(II), Ni(II), Cu(II), and Zn(II) metal salts. All compounds were analyzed by physicochemical, thermogravimetric and spectroscopic techniques. Antimicrobial activity was carried out using the agar-plate method against various strains of bacteria (Staphylococcus aureus, Bacillus subtillis, Pseudomonas aerugionsa, and Escherichia coli) and spores of fungi (Aspergillus niger and Aspergillus flavous). The results showed significantly higher antimicrobial activity of coordination polymers compared to the ligand.
